如何认定“理性”是哲学的任务,也是经济学行为假设的前提。在现代经济学关于理性的讨论中,主流经济学的观点是将其视为一种工具意义的经济理性。1998年,诺贝尔经济学奖得主阿马蒂亚.森站在哲学的层面上,对主流经济学的理性观进行了深刻的批判,从而得出了广义的理性观。广义理性观与我国社会现实具有相容性,值得我们学习借鉴。 How to identify “reason ” is the task of philosophy, but also the premise of economic behavior hypothesis. In modern economics’s discussion of reason, mainstream economics views it as an instrumental economic rationale. In 1998, Amartya Sen, winner of the Nobel Prize in economics, stood at the philosophical level and profoundly criticized the rational view of mainstream economics, thus reaching a broad sense of rationality. The concept of broad sense of rationality is compatible with the social reality of our country and it is worth learning from.
